To al?, whom, zit 11m/y concern: being'practically a fiat-top car andadapted Be it known that I, HENRY P. JOHNSON, for use as such. For effecting this movement residing at Dillon, in the county of Marion I employ a vertical shaft D and a wire rope and State of South Carolina, have made ceror a chain E, Whichis wound around said shaft 5 tain new and useful Improvements in Movand whose ends are attached to the respective 55 able Platforms for Railway-Stations, of which ends of the movable platform A. At a point the following is a specification. intermediate the ends of the latter the rope lily/invention consistsin providing the plator chain E runs on pulleys F, which are pivform of a railway station or depot with a movoted in fixed position in the center of the pasio able section for use in transferring freight sage-way for the platform or car A. The 6o with convenience and despatch. The said shaft D is arranged in suitable bearings in section is flush with the fixed portion of the the platform B and a step-block b. platform and mounted on rollers and ar- It is apparent that by rotating the shaftD ranged to move at a right angle to the edge (by hand or by power) the rope or chain E 15 or side of the platform adjacent to the railwill be taken up on one side and let out on 65 way-track. i the other and the platformA thereby moved The details of construction, arrangement, correspondingly toward or away from the and operation are as hereinafter described, track, so that freight placed thereon may be and shown in the accompanying drawings, easily and quickly conveyed to a car standzo (two sheets,) in whiohing on the track or removed therefrom to the 7o Figure l is a vertical section of my iinrear portion of the fixed platform B or the proved movable section or rolling platform rear portion of the freight-house. The movand a portion of a fixed platform or floor of able platform thus enables freight to be hana freight-house, the line of section being dled much more easily than is practicable by z 5 transversely of said movable platform. Fig. the ordinary method and saves time, labor, 75

Strap or fiat-bar iron is applied platform, having a transverse passage-way, 95 to the under sides of the sills d to take the pairs of rollers C, Xed in such passage-Way, wear incident to use. It is apparent that the two pulleys arranged adjacently and between platform A is thus adapted to be easily moved said rollers, a movable platform arranged in on the rollers O forward and back in the passaid passageway, and having sillsa that rest 5o sage-way or opening in the fixed platform B, and run upon the rollers, and with its top Ioo ush With'the freight-house platform, a rope v attached to the ends of the movable platform and passing over the aforesaid pulleys, and a shaft arranged in the fixed platform, for winding the rope, as shown and described.

2. The combination With a fixed platform or floor, having a transverse passage-Way, of a movable platform arranged in such passageway, and having its top flush with that of the 1o fixed platform, rollers iixed in the passage- Way for supporting the movable platform, a winding-shaft, a rope 0r chain attached to the movable platform, and Wound upon the shaft at an intermediate point, substantially as shown and described.
